JINCHEON, South Korea, Jan. 22 (Yonhap) -- South Korea women's national hockey coach Sarah Murray said Tuesday she has "mixed feelings" about having to coach the joint Korean team at the upcoming PyeongChang Winter Olympics.

At a hastily scheduled press conference at the national team practice rink, Murray said it's "exciting" to coach the first-ever unified Korean team in any sport at the Olympic Games, though she wished it didn't have to come at the expense of her own players.

"It's exciting to be a part of something that's so historic, to have two countries so divided come together through sports," Murray said at Jincheon National Training Center in Jincheon, 90 kilometers south of Seoul. "I think the story is great and to be a part of it is important. But at the same time, it's mixed feelings because it's at the expense of, 'We don't get to play our full roster.'"

The International Olympic Committee (IOC) announced last Saturday North Korea will have 12 players join the current 23-player South Korean squad for the women's hockey tournament at the PyeongChang Winter Olympics. While staying on as the head coach of the unified team, Murray has to put at least three North Koreans into the lineup.

The actual game rosters remained unchanged at 22, with 20 skaters and two goaltenders. Murray would have only needed to leave one player out for each game without the IOC decision. Now, with the start of the Olympics only weeks away, Murray finds herself in a difficult situation of incorporating unfamiliar faces into her system and having to cut four of her own players for each game.

Murray said she doesn't yet know which 12 players from North Korea will come and when, and she added, "I hope they come as soon as possible so we can start practicing right away."

Murray previously said she doesn't think any North Korean player is good enough to crack the top three lines. And she won't just put any North Korean player on the ice just to give them Olympic experience.

"Right now, our plan is we're going to pick the best players. We're trying to win at the Olympics," she said of her 22nd-ranked team that has been on the rise in recent years. "Now our players believe they can win. So we're not going to make a line just to make a line of North Korean players just so they can get ice time. We're going to put in players that are going to be successful and we're going to play to win with the roster we have."

Asked if she was wary of any pressure from political circles to play all North Koreans at least once, Murray said she's been assured she has "the ultimate control."

"As far as I know, I have complete control and I am going to play the players I want," she added.

The two Koreas agreed on forming the joint hockey team on Jan. 9. South Korean Sports Minister Do Jong-hwan first raised the possibility of a single Korean hockey team last June. It appeared to fade away in the face of some criticism, but resurfaced at the start of the new year, after North Korean leader Kim Jong-un said he'd send his athletes to PyeongChang for the Olympics.

The subsequent inter-Korean meetings on the North's participation had the hockey team issue on their agenda, and it didn't take long for the IOC to give its stamp of approval.

South Korea has faced some backlash at home for its push to bring North Korean players on board. Critics of the idea say South Korean players will unfairly lose their playing opportunity and that the government is only using the sport of hockey as a political tool. Supporters of the move say having a few players sit out games is a relatively minor issue when considering a great good -- namely, peace on the Korean Peninsula -- it can possibly achieve.

Murray said she wasn't "really that angry" about how things have led to the joint team and how much she'd been kept in dark, because getting upset was a waste of energy.

"We don't have a lot of days leading up to the Olympics, and we can't waste any extra energy being angry," she said.

The sport of hockey has never been discussed with as much fervor in the country. And Murray said one positive that can come out of this situation is that hockey will generate much interest in the sport.

"So many young athletes are going to see us and get interested, and adding North Koreans gives our sport more publicity," she said. "Hopefully, more people are going to watch and we'll have more female athletes competing in the Olympics in the future."

South Korea is in Group B at the Olympics. Its first game is against world No. 6 Switzerland at 9:10 p.m. on Feb. 10, with fifth-ranked Sweden up next at 9:10 p.m. on Feb. 12. The final group match is against ninth-ranked Japan at 4:40 p.m. on Feb. 14. All games will be played at the Kwandong Hockey Centre in Gangneung.
